Application filed (Jetober 27, 1921. Serial No. 510,870.

To all whom it may concern:

Be it known that I, Gnonen W. NEWMAN, a citizen of the United States, and a resident of the city of Ghica 'o, in the county of Cook and State of I inois, have invented certain new and useful Improvements in Loose-Leaf Books and Methods of Assembly; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a loose leaf book and the method of manufacturing the same.

It is an ob'ect of this invention to provide a structure t at will always retain its shape and improve the a pearance of the binder.

It is a further 0 ect of this invention to provide a binder having separable parts with novel means for attaching them to gether.

It is a further object of this invention to provide a novel rear or backstructure for the binder that tends to reserve the shape of the binder and hold the parts in proper relation.-

his a further object of this invention to provide a novel manner of assembling the parts of the binder.

With these and other objects in view which will be more apparent in the following description and lsclosures, my invention comprises the novel mechanisms and method of assembling hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of my invention and in which similar reference numerals refer to similar features in the difi'erent views: V

Figure 8 is a top plan view of the back plate with the binder cover thereon. Figure 9 is a top plan view of the assembled leaf holding. means with parts of the cover attached.

Figure 10 is a perspective view of the binder in assembled form.

As shown on the drawin The book comprising tfi: sub'ect matter of this invention consists prefera 1y of three parts or units, namely, the cover, the leaf retamlng dev1ce,and the back or rear structure WhlOh 'are provided with novel securmg means, whereby they areassembled and interlocked in a novel way. The cover comprises preferably a piece of pliable leather 1 or composition of leather of such a size as to encompass the sides and bottom of the loose leaves when said leather is folded in itsproper book form. The "illustrated leaf retaining device com- Egises a pair of abutting ring holding memrs 2 retained. in abuttin relation by means of'a downwardly bower? resilient plate 3 having slight lateral grooves formed by bent over lips at its lateral edges for receiving the outer edges of the ring holding members 2. The lower portion of said spring plate 3 is provided with a slot 4 a short distance to one side of the center thereof and slits 5 adjacent the ends as shown in Figure 4. These slits 5 and slot tare preferably arran ed upon the center line of the plate. Ti plates 2 are supported for-conjoint tilting movement. For this purpose cooperating notches are formed in the abutting edges of the plates 2 for loosely receiving the shanks of double-headed rivets or fasteners 8, the heads of which are sufficiently spaced to allow a proper upward or downward tilting movement of said plates. The tiltin of these plates is efi'ected by a pair of pus buttons 7 or the like, which are anchored between said plates in any suitable manner so as not to interfere with the tilting movements thereof, and these push buttons extend through apertures in the back plate e abutting edges of the of the rear structure where they are prostuds 14, then applying the lea Vided with curved heads resting against the sheath of theback plate so as to be operable bpressure against the outer surface of said eath. At proper intervals, the ring plates 2 are provided with the opposed ring members 8 that hold the loose leaves. The structure of the leaf holding means, however, forms no part of my present invention except in so far as it is provided with means or constructed to cooperate with my invention.

The leaf retaining means or device is preferably provided with. a resilient notched cover plate 9 having lateral lips which snap over the spring plate 3, but itshould be understood that this cover plate 8 is not applied until the book is completely assembled in other respects, and does not necessarily constitute a part of the leaf. holding device as described in this specification.

The rear structure which comprises part of my invention is adapted to be applied to the outside of the cover 1 to form the back of the book consists preferably of an outwardly bowed or curved back plate 10 sheathed by means of a suitable piece of leather 11 or the like; the sheath covering the outer bowed portion and overlapping the lateral edges for a considerable extent inwardly as shown in Figure 3. The sheath may be glued or otherwise secured to the plate 10. The endsof the sheath 11 are rovided with flaps 12 having slits 13 as est shown in Figures7 and 8, and the back late 10 is (provided with upwardly or inward y directe tongues or lugs 14 adapted for entering said slits when the flaps 12 are superimposed thereon. The plate 10 is further provided with a holding tongue or lug 15 at the center thereof. The tongues 14 and lug 15 of the back plate 10 are adapted to pierce the cover 1 which is provided with suitable slits at the proper center line for this purpose as shown in Figure 8, and be anchored in the slots 5 and'4 of the spring plate 3 respectively. The slots 4 and 5 in the spring late 3 are broadly termed sockets to receive t e tongues 14 and 15 of the back plate 10.

The method of assembling the different parts consists in placing the sheathed plate or rear structure upon its back, placing the cover thereover with the slits thereof engaging the tongues 14 and 15 as best shown in Figure 8 and superimposing the flaps 12 over the cover with the slits 13 enfgaging the retalning device thereupon by a slightendwise movement to bring the wall of the slot-4 thereof under the In or tongue 15 as'best shown in Figure 5 an the slots 5 in a position to engage over the ton es 14; if necessary, the parts may be slightly flexed for this purpose. The tongues 14 are then crimped over the upper surface of the sprin plate 3 (Figure 5) and the cover 9 applie o the leaf retaining device; then oy folding the sides into book form as shown in Figure 10, the binder will be complete and ready for use It is characteristic of my invention that the plates 3 and 10 are provided with mutual- 1y engaging tongues and sockets, the tongues overlapping the walls of the sockets wherethe parts are securely interlocked together, and that the rear structure or sheathed plate is provided with flaps that overlap the cover and retain the same, in consequence of which the different parts may be said to be interlocked together by overlapping parts.

It should be noted that the cover 1 is securely anchored between the plates 3 and 10, being supported by the plate 3, and that the rear structure provides a rigid support 1 therefor holding the parts in proper relation I and insuring long service and a good booklike structure'that is not readily liable to break or tear and that safety retains the leaves from being torn therefrom or mutilated by a relative endwise shifting of the covers."

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my'invention: 7 r
